MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 743,379, dated November3, 1903.

Application filed October 27, 1902. Serial No. 129,043. (No model.)

To otZZ whom it may concern.-

Be it known that we, FREDERICK M. DIL- LON, a citizen of the UnitedStates of America, and WYLIE G. WILSON, a subject of the King of GreatBritain, both residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements inMechanical Movements; and we do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in'the art to which it appertains to make and use thesame, reference being bad to the accompanyingdrawings,

and to the figures of reference marked thereon, which form a part ofthis specification.

Our invention relates to improvements in mechanical movements, and ismore especially intended for imparting a vibratory action toconcentrating-tables, and it will be described in that connection inthis specification.

Our object is to provide a device of. this class which shall becomparatively simple in construction, economical in cost, reliable,durable, and eflicient in use; and to these ends the invention consistsof the features, arrangements, and combinations hereinafter describedand claimed, all of which will be fully understood by reference to theaccompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a top or plan view of our improvedconstruction. Fig. 2 is a section taken on the line 2 2, Fig. 1. Fig. 3is a side elevation of the device shown in connection with aconcentrating-table.

The same reference characters indicate the same, parts in all the views.a

Let the numeral 5 designate a suitable castiron frame provided with twoupwardly-projecting side parts 5, connected at their ends by transverseparts 5. The parts 5 are provided intermediate the parts 5 with depending lugs 5, connected by a shaft 6, which forms the fulcrum for anupright lever 7,

. whose lower extremity engages the said shaft.

The upper extremity of this lever engages the forward end of theconcentrating-table 8 or other part to be vibrated. The movement of thelever imparts the rearward movement to the concentrating-table, while aspring 9, suitably located, imparts the return or forward movement, andits tension holds the head end of the table against the adjacent 1 part7 of the lever. This lever is provided with forwardly-projecting lugs 7and 7 in jwhich an adjusting-screw 10 is journaled. These lugs areseparated, and between them j is located an abutment or distance-piece12, i which is threaded on the screw and vertically movable whenthelatter is turned. The abutment has a flat surface and closely engagesthe adjacent part of the lever 7, which is of corresponding shape,whereby the abutment is prevented from turning with the screw and ismade to travel up and down thereon, according to the direction ofrotation.

In front of the abutment and engaging the same is a swinging oroscillating block or lever 13, whose upper extremity is loosely mountedon an eccentric collar formed on a shaft 14:. The front surface of thisblock 13 is curved, as shown at 13, to engage an cecentric bearing orcam 15, formed on an opcrating-shaft 16, one extremity of which isprovided with a pulley 17, while the other extremity is provided with afly-wheel 18.

In the operation ofthe apparatus power is applied to rotate the shaft16, and the eccentric 15, acting'on the block 13, actuates the latter,which in turn engages the abutment 12 and actuates the lever 7, whoseupper extremity moves rearwardly or in the direction of the arrow inFig. 2, whereby the concentrating-table is forced against the spring 9,which in turn imparts the forward movement to the table, the lever, theabutment, and the block 13, whereby the latter is held in contact withthe eccentric collar 15 of the shaft 16. In this way a constantvibration is imparted to the table or other apparatus to be actuated.

The length of the vibratory stroke or movement is regulated by adjustingthe parts 12 and 13. If the part'12 is moved upwardly on the screw, thelength of its stroke is shortened, while if this part moves downwardlythe opposite result is obtained and the stroke is lengthened. By turningthe shaft 14 the block 13 may have its vertical and longitudinalposition changed to a limited extent, whereby the stroke is varied byreason of the curved face 13, which is engaged by the eccentric 15.

Having thus described our invention, what we claim is 1. In a mechanicalmovement, the combination with a suitable frame, of a lever fulcrumedthereon and engaging the part to be vibrated, an operating-shaftprovided with a cam, and means interposed between the lever and the camof the shaft for actuating the lever, said means comprising anotherlever, and an abutment adjustable on the firstnamed lever and interposedbetween the fulcrum-points of the two lovers, the arrangement being suchthat as the abutment is moved in either direction it approaches onefulcrum-point and recedes from the other fulcrum-point.

2. The combination with a suitable frame, and a part to be vibrated, thelatter being spring-actuated in one direction, of a lever fulcrumed onthe frame and arranged when actuated to force the said part against itsspring, a swinging block located in front of the lever and arranged,when moved, to actuatethe lever, an operating-shaft, an eccentricthereon which engages the block, said block and the lever normallyoccupying positions substantially parallel, the fulcrumpoint of thelever and the center of movement of the block, being remote from eachother, and an abutment mounted on the lever and longitudinally movablebetween the said points, the abutment forming a bearing for the block.

3. In a mechanical movement, the combination with a concentrating-tablespring-actuated in one direction, of a lever arranged .when actuated tomove the table against the spring, an abutment mounted on the lever andlongitudinally movable, anoperatingshaft provided with an eccentric, andmeans interposed between the eccentric and the abutment for actuatingthe lever, and means comprising another lever bearing against theabutment which is located between the fulcrum-points'of the two levers,whereby as the abutment is moved toward the fulcrum-point of one lever,it recedes from the corresponding point of the other lever.

4. The combination with a suitable frame, of a lever fu'lcrumed thereon,a screw journaled on the lever, an abutment threaded on the screw andadjustable by turning'the latter, and suitable operating means foracting on the abutment to operate the lever, com prising a second leverbearing against the abutment which occupies a position between thefulcrum-points of the two levers, the arrangement being such that whenthe abutment is moved it approaches one fulcrumpoint as it recedes fromthe other corresponding point, and an operating-shaft having aneccentric engaging the second lever.

5. The combination with an operating-shaft provided with an eccentric,and a part to be vibrated, of an actuating block 7 having a curved faceengaged by the eccentric of the shaft, said block being mounted on aneccentric for purposes of adjustment, and suitable means interposedbetween the said block and the part to be vibrated, comprising a leverand an abutment longitudinally movable thereon, the abutment beinglocated between the center of movement of the block and the fulcrum ofthe lever, one of these points being on each sideof the abutment, andthe arrangement being such that as the abutment is moved on its lever,it approaches one of said points while it recedes from the other point.

6. Thecombinationwithanoperating-shaft provided with an eccentric and apart to be vibrated, of a lever suitably fulcrumed, a screw jour'naledon the lever, an abutment threaded on the screw, and an oscillatingblock interposed between the abutment and the eccentric on the shaft,the said block being adjustable and having a curved face engaged by theeccentric, the abutment being located between the center of oscillationof the block and the fulcrum-point of the lever, the arrangement beingsuch that as the abutment is moved on the screw, it recedes from one ofsaid points and approaches the other.

7. The combination with a suitable frame and a spring-held part to bevibrated, of two levers one of which actuates the part to be vibrated,suitable means for actuating the other lever, one of said levers havingits fulcrum at one extremity and the other lever having its fulcrum atits opposite extremity, and an adjustable distance-piece interposedbetween the two levers and between their fulcrums whereby the movementof the distance-piece causes it to recede from the fulcrum of one leveras it approaches the fulcrum of the other lever.

ICO

8. In a mechanical movement, the combination of two levers one of whichis fulcrumed at one extremity, the other of which is fulcrumed at theopposite extremity, and an adjustable distance-piece interposed betweenthe two levers located intermediate their fulcrums and movablelengthwise of the levers, whereby as the abutment recedes from thefulcrum of one lever it approaches the fulcrum of the other lever, andsuitable means for actuating one of thelevers whereby motion iscommunicated to the other lever through the distance-piece.

In testimony whereof we affix our signatures in presence of twowitnesses,
